AI-Powered SAP ABAP Code Remediation for S/4HANA

SAP Custom Code Remediation for S/4HANA

The technical conversion to S/4HANA is well understood and largely tooled. What takes the time is the code your organization wrote: the reports, the enhancements, the interfaces, the workarounds that solved a problem in 2012 and have been running ever since.

SAP custom code remediation is the work of telling three things apart across thousands of objects. Some code breaks outright on S/4HANA. Some runs, but runs badly, because logic written against a row store behaves differently on a column store. Some of it nothing calls any more, and remediating that is money set on fire.

Why Custom ABAP Becomes a Migration Problem

A remediation program priced the conventional way assumes a consultant opens each object, reads it, decides what to do and does it. That is a sound method, and it is why the estimates are large. The cost is not the difficulty of any single fix, since most are routine. It is the volume multiplied by the reading.

Agents change that ratio. An agent reads a program it has never seen, works out what it does, identifies why it will fail on S/4HANA, and produces a compliant rewrite. The unit of work moves from consultant-weeks to runtime minutes. On recent estates that has meant two days of agent work where the conventional estimate was two months. What stays human is the decision about whether the rewrite is right, which is a far faster thing to do than the rewrite itself.

What Our AI Agents Analyze

SAP custom code analysis covers the full custom repository rather than a representative sample: every program, report, function module, class and include in the custom namespace, the enhancements and user exits layered onto standard SAP, the interfaces and integration points, the custom tables and data dictionary objects, and the runtime statistics behind all of it.

Full coverage is the point. A sampled survey tells you roughly how bad things are. An inventory tells you which objects, which constructs inside them, and what each one costs.

Identify Code to Retain, Remediate or Retire

The cheapest object to remediate is the one you delete. Runtime statistics show what has actually executed rather than what merely exists, and in most estates a meaningful share of custom code has not run in years: superseded reports, abandoned interfaces, programs written for a process that changed.

We produce a retirement list with the evidence attached, so the decision to drop an object rests on execution data rather than on whether anyone remembers what it was for. Every object on that list is S/4HANA custom code remediation effort you get to decline. On a typical estate this is where a large part of the saving comes from, before a single line is rewritten.

AI-Assisted ABAP Remediation

For everything worth keeping, the agents produce S/4HANA-compliant, HANA-optimized ABAP held to your own naming and structure conventions. Not a black box, and not a transpiled artifact your team cannot maintain. Remediated code is usually more readable than what it replaced, because the rewrite strips the dead branches and undocumented workarounds that accumulated over a decade.

SAP Architect Review

Nothing an agent produces reaches your transport path without an SAP architect reading it and signing it off. The review catches what the agent cannot know: that this program is being decommissioned anyway, that this apparently redundant check exists because of a regulatory requirement, that this interface has a consumer nobody documented.

You receive the review log with the work: every change, who reviewed it, and what they altered. That record is what makes AI ABAP remediation defensible to whoever owns the system.

Functional Parity Validation

Rewritten code with an assurance attached is a different thing from rewritten code with evidence attached. We generate regression coverage against the original behavior and run it before and after, so functional parity is demonstrated rather than asserted. This is why SAP ABAP remediation is usually scoped alongside automated testing. Asking a business to take parity on trust is asking for something they are right to refuse.

HANA Optimization

There is a low bar for remediation: change what the syntax checker complains about and move on. That clears the conversion and leaves the performance problem intact, because the code is still doing row-store things on a column store, with nested selects inside loops, logic in ABAP that belongs in the database, and full-table reads where a filtered aggregate would do.

ABAP modernization done properly pushes that work down to HANA. It is why the performance figures in our case studies come out of remediation projects rather than from separate tuning exercises: the same pass that makes the code compliant makes it fast. Where an estate needs deeper work, SAP ABAP optimization continues after the migration blockers are cleared.

What You Receive

• Break analysis across the full repository. Every custom object read and classified: what fails on S/4HANA, what runs but runs badly, what is already compliant.
• An evidence-backed retirement list. Objects with no execution history, with the runtime data attached, so you can decline the work defensibly.
• HANA-optimized rewrites. Logic pushed down to the database, loops and nested selects restructured, full-table reads replaced.
• An architect review log. Every change, the reviewer, and what they altered.
• Parity evidence where testing is in scope, showing the rewritten code behaves as the original did.
• A manual-work list. The objects an agent should not touch, flagged during triage and quoted separately.

ABAP Remediation Use Cases

• Clearing the blockers before an S/4HANA conversion. The classic case, and the one with a deadline attached.
• SAP custom code migration after a landscape assessment. The scored inventory from the readiness assessment becomes the input, so nothing is analyzed twice.
• Shrinking the estate without migrating. Retirement and optimization stand on their own merits. A smaller, better-understood custom estate is worth having whether or not the date moves.
• Catching up a stalled remediation backlog. Programs where the manual effort is falling behind the discovery rate.
• Post-conversion cleanup. Estates that converted under time pressure carry code that was made to compile and never made to work properly.
• Preparing for an audit or a handover. The review log and the rewritten code leave the next team something readable.

Case Studies and Results

Measured results from production estates where agents did the remediation and optimization work. Each is written up as a case study on this site.

• Over 100,000 lines of ABAP refactored across delivered engagements
• Two days of agent work against a two-month conventional estimate on a recent remediation
• Up to 99% faster SAP reporting for a global footwear manufacturer
• Up to 80% faster ABAP reports for a global cement manufacturer
• 70% faster dispatch and billing workflows for a global steel manufacturer

In every case the functional output was unchanged. Only the time taken moved. Read the case studies.

Why 2iSolutions

Twenty years of SAP delivery sits behind the agents. We have been a certified SAP partner since 2005 and have run implementations, conversions and support across the United States and Canada since then.

The agents compress the reading. The judgment stays with architects who have delivered SAP for two decades, and no change reaches your system without one of them signing it.
